Filed: 2002-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging (MRI) equipment capable of surely imaging a flow of a low flow velocity such as a blood stream of lower limbs without administering a contrast medium. SOLUTION: In this MRI equipment, in the state where an operator roughly matches an impressing direction of read gradient magnetic field pulse GR with a flowing direction of the blood stream of the lower limbs for instance, scanning is executed corresponding to a prescribed heart time phase to collect echo signals and arteriovenous separation images for instance of the blood stream are generated from the echo signals. To the read gradient magnetic field pulses GR, strength-changeable dephase pulses Pdephase are added as phase action control pulses respectively before and after the pulse main body timewise.  By matching the impressing direction of the read gradient magnetic field pulses GR with the flowing direction of the blood stream and impressing the dephase pulses Pdephase , a difference of a flow void effect is generated corresponding to a flow velocity of the blood and the arteriovenous separation images are generated on the basis of the relative difference of signal values due to the difference.
